United States Patent Ofiiice 3,029,443 Patented Apr. 17, 1962 3,029,443 CLOSED PRESSURE TYPE FLUSH TANK BOWL COMBINATION Tony C. Naccarato, 1939 Pepper St., Burbank, Calif. Filed Nov. 2, 1959, Ser. No. 850,351 9 Claims. (Cl. 4-26) The present invention relates to an improved flush-type tank and bowl combination for use in a toilet and which has to do with an unusually simplified construction and arrangement of parts and which involves the use of a closed system.

It is submitted that there are many situations and conditions where a predetermined charge of flush water from a tank to a bowl with a valved pipe connection between the two may well be satisfactorily adopted and effectually utilized. Moreover, there has long existed the problem of how to go about dispensing with complicated leaky toilet facilities of currently used constructions. Stated otherwise, since the ordinarily used flush tank involves a fill pipe, a discharge seat with a liftable and lowerable tank ball, a float controlled valve operating arm and numerous ways of manually and otherwise tripping the tank ball, exasperating conditions and the nuisance of attempting to cope with the same are ever-present.

The instant concept has posed not only the problem but how best to classify and solve it. That this has been achieved quite simply and successfully will become apparent by way of the almost self-evident ideas and reduction to practice herein revealed.

In carrying out the principles of the solution under advisement the usual sectional tank, that is, with a removable cover, and all of the mechanism or equipment thereon is herein dispensed with. A simple water-tight container or tank is substituted therefor. One end of the tank is connected by a valved controllable line to the toilet bowl. A relatively small and inexpensive city service supply line from the street main or piping in the house is communicatively connected with the water space or reservoir in the tank. In fact, all that is necessary to complete this unique concept is to introduce an inflatable and deflatable bladder-like bag in the reservoir. It follows that the incoming water under pressure compresses or partially deflates the bag and the surrounding water in the reservoir is placed under pressure and is ready to be expelled. In fact, by simply opening the valved line between the tank and the toilet bowl the water rushes out quite forcibly and manifestly flushes the bowl.

Other objects, features and advantages will become more readily apparent from the following description and the accompanying drawings.

In the drawings, wherein like numerals are employed to designate like parts throughout the views:

FIG. 1 is a front elevation showing a conventional toilet bowl and the improved flush tank and how it is constructed and operatively combined with the bowl;

FIG. 2 is a side view, that is, a view which may be said to observe the construction seen in FIG. 1 in a direction from left to right;

FIG. 3 is a section, with parts in elevation, on the vertical line 33 of FIG. 2 looking in the direction of the arrows;

FIG. 4 is a view showing a modified construction with the underlying principles the same; and

FIG. 5 is a view of the construction seen in FIG. 4 in a direction at right angles thereto.

Reference may be had first to FIGS. 1 to 3. In FIG. 1 the conventional toilet bowl is denoted by the numeral 8. One section of a valved pressurized water delivery line or conduit 12 is suitably connected to the bowl, The other section 14 is connected to the bottom portion 16 of a horizontally elongated closed container here referred to as a flush tank '18. The line 12 is provided with a suitable valve 2! and a push-pull control handle 22 therefor. .The city service small pipe line at the right embodies a vertical section 24 also connected to the bottom of the tank and has a suitable cut-off valve at 26 as shown in FIG. 2. The tank as a unit is embraced by suspension bands 28 carried by brackets 30 (FIG. 2) suitably mounted on the Wall or other support surface 32. As seen in FIG. 3 the tank or container may be made up of half-sections 34 with their flanged abutting ends 36 connected together by an embracing and connecting channel 36 providing, of course, a suitable fluid-tight water space or reservoir 38. The elongated inflatable and deflatable or expansible and contractible pressurizing means or device comprises a bladder-like elastic or an equivalent bag 40 suitably adapted to the reservoir space. In practice this bag is of course charged with compressed gas and it will be obvious that water from the inlet line 24- entering the reservoir squeezes and compresses the bag and conditions the charge of water for ready expulsion. It follows that when the valve means 20 and 22 is operated and the line 12 is opened the water in the reservoir 38 is forcibly expelled from the tank and delivered to the toilet bowl in the manner to flush the same.

With respect to the slight modification seen in FIGS. 4 and 5, the principles of construction are the same. Here the toilet bowl is denoted at 42 and the valved flush water delivery line at 44. A delayed action magnetic control valve 46 is embodied in this line and is operated by a push button 48 having suitable operating connection at 50 to the valve. The pipe section 52 is communicatively connected to the body 54 of the vertically r elongated stand-type flush tank 56. The body has supporting feet 58, a cap or top section 60 with the flanged portions 62 joined by a connecting channel 64. The inlet line is denoted at 66 and the cut-off valve at 68. The mode of operation here is the same as already described.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling Within the scope of the invention as claimed.

What is claimed as new is as follows:

1. For use in pressurizing and forcibly expelling a limited quantity of water for ready use; a fluid-tight container having a fluid trapping space providing a temporary reservoir for the water, an inlet pipe operatively connected with said container and constantly communicable with said reservoir and serving to fill the reservoir with water and under service pressure, an outlet pipe also operatively connected with the container and reservoir, and at least one hermetically sealed inflated but contractible water expelling device floating but confined in the reservoir and which is charged with compressed gas, said device being contracted by the confined surrounding water and being thus contracted and placed under ready-to-expand pressure, whereby when the valve in the outlet pipe is properly opened, the expelling device automatically resumes its expanded state and forcibly displaces the trapped water by way of said discharge pipe, said inlet pipe being connectible with a city main, and said outlet pipe being connectible with a flush-type toilet bowl.

2. For use in pressurizing and forcibly expelling a limited quantity of water for ready use; a fluid-tight container having a fluid trapping space providing a temporary reservoir for the water, an inlet pipe operatively connected with said container and constantly communicable a r with said reservoir and serving to fill the reservoir with Water under service pressure, an outlet pipe also operatively connected with the container and reservoir, and at least one inflated but contractible hermetically sealed water expelling device entirely confined in the Water reservoir and which is charged with compressed gas, said device being contracted by the confined surrounding water and being thus contracted and placed under ready-toexpand pressure, whereby when the valve in the outlet pipe is suitably opened, the expelling device automatically resumes its expanded state and forcibly displaces the trapped water by way of said discharge pipe, and a flushtype toilet bowl to which said outlet pipe is communicatively connected, said container comprising a flush-tank free of the usual float-controlled valve and trip means. 3. In combination, a toilet flush tank in the form of a fluid-tight container having an interior space defining a flush Water trapping and storing reservoir, inlet and discharge pipe means operatively connected with said container and constantly communicable with said reservoir and serving to fill and empty the reservoir with water under service pressure, and at least one inflated but contractible water expelling device confined in the reservoir and which is charged with compressed gas, said device floating in and being contracted by the confined surrounding water and being thus contracted and placed under ready-to-expand pressure, whereby when a valve in the outlet pipe is suitably opened, the expelling device automatically resumes its expanded state and forcibly displaces the trapped water by way of said discharge pipe.
